DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the inventive concept will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings and specification may denote like elements, and to the extent that a description of these elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

FIG. 1 is a perspective view illustrating a solid state drive (SSD) apparatus 10 according to example embodiments of the inventive concept. FIG. 2 is an exploded perspective view illustrating the SSD apparatus 10 according to example embodiments of the inventive concept. FIG. 3 is a cross-sectional view illustrating the SSD apparatus 10, taken along line X-X′ of FIG. 1 . FIG. 4 is a cross-sectional view illustrating the SSD apparatus 10, taken along line Y-Y′ of FIG. 1 .

Referring to FIGS. 1 to 4 , the SSD apparatus 10 may include a case 100, a substrate 210 disposed within the case 100, and a semiconductor chip 220 disposed on the substrate 210.

The case 100 may form an exterior of the SSD apparatus 10. The case 100 may have a three-dimensional shape including an accommodation space 109 in which the substrate 210 and the semiconductor chip 220 are accommodable. For example, the case 100 may include an upper wall UW having a plate shape, a lower wall LW having a plate shape and facing the upper wall UW, and side walls connecting the upper wall UW to the lower wall LW. For example, the case 100 may have a square pillar shape having four side walls including a first side wall SW1 and a second side wall SW2 facing each other and a third side wall SW3 and a fourth side wall SW4 facing each other. However, the shape of the case 100 is not limited thereto, and the case 100 may have a polygonal pillar shape such as a pentagonal pillar or a hexagonal pillar, or a cylindrical shape.

The case 100 may include an uppercase 101 and a lower case 103, which are detachably coupled. The upper case 101 may be coupled onto the lower case 103 to form the accommodation space 109 therebetween. The upper case 101 may include at least a part of the side walls of the case 100 and an entirety of the upper wall UW of the case 100. The lower case 103 may include at least a part of the side walls of the case 100 and an entirety of the lower wall LW of the case 100.

The case 100 may include a material having a high thermal conductivity (e.g. a thermal conductivity of at least 10 W/m K) so as to more easily discharge heat generated from the semiconductor chip 220 to the outside. As used herein, the phrase “outside” is intended to mean a space outside the case 100. The case 100 may include a single material or a combination of different materials. The case 100 may include a metal, a carbon-based material, a polymer, or a combination thereof. The case 100 may include, for example, copper (Cu), aluminum (Al), zinc (Zn), tin (Sn), stainless steel, or a clad metal including one or more of the same. Alternatively, the case 100 may include, for example, graphite, graphene, a carbon fiber, a carbon nanotube composite, or the like. Alternatively, the case 100 may include, for example, an epoxy resin, polymethylmethacrylate (PMMA), polycarbonate (PC), polyethylene (PE), polypropylene (PP), or the like.

According to example embodiments of the inventive concept, the upper case 101 and the lower case 103 may be produced by extrusion and machining. In this case, each of the upper case 101 and the lower case 103 may be made of a single member without a breakpoint, and thus, a thermal diffusion ability thereof may be increased.

The case 100 may include an inner plate 110 which separates or partitions an inner space of the case 100 into an air tunnel 130 and the accommodation space 109. For example, the inner plate 110 may be a plate-shaped member parallel to the upper wall UW and may be a part of the upper case 101. The air tunnel 130 may be provided between the inner plate 110 and the upper wall UW of the case 100 and may be enclosed within the side walls of the case 100. In addition, the accommodation space 109 may be provided between the inner plate 110 and the lower wall LW of the case 100 and may be enclosed within the side walls of the case 100.

The air tunnel 130 may be a passage formed in the case 100 so as for air to flow therethrough. For example, the air tunnel 130 may be a passage extending primarily in a first direction (e.g., Y direction) from the second side wall SW2 to the first side wall SW1. As used herein, the phrase “extending primarily in a direction” is understood to mean that a longest dimension of the object being referred to extends in the given direction even though it is understood that the object has inferior dimensions that extend in other directions.

For example, when an external cooling fan operates to force air around the SSD apparatus 10 to flow in the first direction, the air may flow in the first direction along the air tunnel 130, such that heat of the SSD apparatus 10 is discharged through heat exchange between the air and the case 100. According to example embodiments of the inventive concept, a second end part 130E2 of the air tunnel 130 exposed through the second side wall SW2 may be an inlet through which external air flows in, and a first end part 130E1 of the air tunnel 130 exposed through the first side wall SW1 may be an outlet through which the external air flows out.

According to example embodiments of the inventive concept, a plurality of air tunnels 130 may be provided between the inner plate 110 and the upper wall UW of the case 100. Each of the plurality of air tunnels 130 may be spaced apart from each other by a plurality of separation walls 120 disposed between the inner plate 110 and the upper wall UW. The plurality of separation walls 120 may be a part of the upper case 101 and may be contiguous therewith.

Each of the plurality of separation walls 120 may extend primarily in the first direction from the second side wall SW2 to the first side wall SW1. In this case, each air tunnel 130 may be defined by two neighboring separation walls 120, the inner plate 110, and the upper wall UW or defined by a side wall of the case 100, a separation wall 120, the inner plate 110, and the upper wall UW. According to example embodiments of the inventive concept, the plurality of separation walls 120 may extend primarily in the first direction so as to be parallel to each other and may be spaced apart from one another at uniform intervals in a second direction (e.g., X direction) orthogonal to the first direction.

The separation walls 120 may help to establish a constant air flow in the first direction inside the air tunnels 130 and suppress generation of a vortex causing a disturbance of heat transfer between air and the case 100. In addition, by providing the separation walls 120 between the inner plate 110 and the upper wall UW of the case 100, a heat exchange area between the case 100 and air flowing along the air tunnels 130 may increase, thereby increasing a heat-dissipating characteristic of the SSD apparatus 10.

The substrate 210 and the semiconductor chip 220 may be arranged in the accommodation space 109 of the case 100. The semiconductor chip 220 may be mounted on the substrate 210 by, for example, a ball grid array (BGA) scheme, a pin grid array (PGA) scheme, a tape carrier package (TCP) scheme, a chip-on-board (COB) scheme, a quad flat non-leaded (QFN) scheme, a quad flat package (QFP) scheme, or the like. For example, the semiconductor chip 220 may be mounted on either an upper surface or a lower surface of the substrate 210. Alternatively, the semiconductor chip 220 may be mounted on both the upper surface and the lower surface of the substrate 210.

According to example embodiments of the inventive concept, the substrate 210 may be a printed circuit board (PCB). For example, the substrate 210 may be a double-sided PCB or a multi-layer PCB. The substrate 210 may include a base layer. The base layer may include a phenol resin, an epoxy resin, and/or polyimide. The base layer may include, for example, frame retardant 4 (FR4), tetrafunctional epoxy, polyphenylene ether, epoxy/polyphenylene oxide, bismaleimide triazine (BT), thermount, cyanate ester, polyimide, and/or a liquid crystal polymer.

The substrate 210 may include a wiring layer formed on both an upper surface and a lower surface of the base layer. When the base layer includes a plurality of layers, wiring layers may be formed between the plurality of layers. The substrate 210 may include a conductive via electrically connecting the wiring layers located on different layers in the base layer. The conductive via may electrically connect the wiring layers located on different layers by partially or completely penetrating the base layer. The wiring layer and/or the conductive via may be made of Al, Cu, nickel (Ni), and/or tungsten (W).

A solder resist layer covering apart of the wiring layers on the upper surface and the lower surface of the base layer may be formed on the upper surface and the lower surface of the substrate 210. A part which is not covered by the solder resist layer among the wiring layers on the upper surface and the lower surface of the base layer may be used as a pad to be electrically connected to the semiconductor chip 220, an active device, or a passive device attached to the upper surface and/or the lower surface of the substrate 210.

The semiconductor chip 220 may include a controller chip 221, a first memory semiconductor chip 223, and a second memory semiconductor chip 225 mounted on the substrate 210.

The controller chip 221 may be configured to control both the first memory semiconductor chip 223 and the second memory semiconductor chip 225. A controller circuit may be equipped within the controller chip 221. The controller circuit may control access to data stored in the first memory semiconductor chip 223 and the second memory semiconductor chip 225. The controller circuit may control a write/read operation for flash memory or the like in response to a control command of an external host. The controller circuit may include a separate control semiconductor chip such as an application specific integrated circuit (ASIC). The controller circuit may be configured to be automatically activated by an operating system of the external host when, for example, the SSD apparatus 10 is connected to the external host. The controller circuit may provide a standard protocol such as parallel advanced technology attachment (PATA), serial advanced technology attachment (SATA), small computer system interface (SCSI) standard, or parallel component interconnect express (PCIe). In addition, the controller circuit may perform wear leveling, garbage collection, bad block management, and/or error correcting code for driving of a nonvolatile memory device. In this case, the controller circuit may include a script for automatic execution and an application program executable by the external host.

The first memory semiconductor chip 223 may be a nonvolatile memory device. The nonvolatile memory device may include, for example, flash memory, phase-change random access memory (PRAM), resistive random access memory (RRAM), ferroelectric random access memory (FeRAM), magnetic random access memory (MRAM), or the like but is not limited thereto. The flash memory may be, for example, NAND flash memory. The flash memory may be, for example, V-NAND flash memory. The nonvolatile memory device may include a single semiconductor die or several stacked semiconductor dies.

The second memory semiconductor chip 225 may be a volatile memory device. The volatile memory device may include, for example, dynamic random access memory (DRAM), static random access memory (SRAM), or the like but is not limited thereto. The volatile memory device may provide a cache function of storing data frequently used when the external host accesses the SSD apparatus 10, such that an access time and a data-transfer performance are scaled to meet the process performance of the external host connected to the SSD apparatus 10.

A resistor, a capacitor, an inductor, a switch, a temperature sensor, a direct current (DC)-DC converter, an active device, and/or a passive device may be further mounted on the substrate 210 of the SSD apparatus 10.

An external connector 230 may be disposed at a first edge of the substrate 210 facing the first side wall SW1. The external connector 230 may be exposed through a groove in the first side wall SW1. The external connector 230 may be inserted into a socket of an external device and may electrically connect the SSD apparatus 10 to the external device. Through the external connector 230, the SSD apparatus 10 may transmit and receive a signal to and from the external device and receive power from the external device.

A thermal interface material may be disposed between the semiconductor chip 220 and the inner plate 110. For example, as shown in FIG. 4 , a first thermal interface material 241 may be disposed between the controller chip 221 and the inner plate 110 and additionally disposed between the first memory semiconductor chip 223 and the inner plate 110. The first thermal interface material 241 may also be disposed between the second memory semiconductor chip 225 and the inner plate 110. The first thermal interface material 241 may physically fix the semiconductor chip 220 to the inner plate 110 and reinforce thermal coupling between the semiconductor chip 220 and the inner plate 110. In addition, a second thermal interface material 243 may be disposed between the substrate 210 and the lower wall LW of the case 100. The second thermal interface material 243 may physically fix the substrate 210 to the lower wall LW of the case 100 and reinforce thermal coupling between the substrate 210 and the lower wall LW of the case 100. In addition, when the semiconductor chip 220 is disposed on the lower surface of the substrate 210, a thermal interface material may be disposed between the semiconductor chip 220 on the lower surface of the substrate 210 and the lower wall LW. For example, the first thermal interface material 241 and the second thermal interface material 243 may each include an insulating material or a material capable of maintaining an electrically insulating property by including an insulating material.

Recently, the performance of electronic apparatuses such as a central processing unit (CPU), a memory device, and a storage device has been sharply increasing every year. To maximally use the performance of electronic apparatuses, a system architecture and a communication protocol also require a high-speed operation that supports the enhanced performance, and thus, a PCI communication protocol supports 8 Gbps (Gen3) at present, and a data transfer rate is increasing to 16 Gbps (Gen4) in 2020 and 32 Gbps (Gen5) in 2021. As such, although the performance of electronic apparatuses is increasing according to an increase in an input and output (IO) speed, more heat is generated according to more power consumption on the contrary, and the reliability of the SSD apparatus 10 may be lowered due to this thermal issue.

According to example embodiments of the inventive concept, the case 100 of the SSD apparatus 10 may include the air tunnel 130 in which air flows. Because the case 100 heated by the semiconductor chip 220 and the like may be cooled down while air flows through the air tunnel 130, a heat-dissipating characteristic of the SSD apparatus 10 may be increased, and eventually, the reliability of the SSD apparatus 10 may be increased.

FIGS. 5 and 6 are cross-sectional views illustrating an SSD apparatus 10 a according to example embodiments of the inventive concept. FIG. 7 is a perspective view illustrating an upper case 101 a of the SSD apparatus 10 a shown in FIGS. 5 and 6 .

The SSD apparatus 10 a shown in FIGS. 5 to 7 may be substantially the same as or similar to the SSD apparatus 10 described with reference to FIGS. 1 to 4 except that a vent hole 111 is formed in the inner plate 110. For convenience of description, a difference from the SSD apparatus 10 described with reference to FIGS. 1 to 4 will be mainly described and to the extent that description of other elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

Referring to FIGS. 5 to 7 , the inner plate 110 may include the vent hole 111 penetrating the inner plate 110. The vent hole 111 of the inner plate 110 may connect the air tunnel 130 with the accommodation space 109. While air flows in the first direction (e.g., the Y direction) in the air tunnel 130, heated air in the accommodation space 109 may flow in the air tunnel 130 through the vent hole 111 and flow out to the first end part 130E1 of the air tunnel 130 together with air which has flowed in through the second end part 130E2 of the air tunnel 130.

FIG. 8 is a perspective view illustrating an upper case 101 b of an SSD apparatus 10 b, according to example embodiments of the inventive concept, and FIG. 9 is a perspective view illustrating the SSD apparatus 10 b, from which an upper case 101 b is omitted, according to example embodiments of the inventive concept. FIGS. 10 and 11 are cross-sectional views illustrating the SSD apparatus 10 b according to example embodiments of the inventive concept.

The SSD apparatus 10 b shown in FIGS. 8 to 11 may be substantially the same as or similar to the SSD apparatus 10 described with reference to FIGS. 1 to 4 except that the SSD apparatus 10 b further includes a first inner fan 141. For convenience of description, a difference from the SSD apparatus 10 described with reference to FIGS. 1 to 4 will be mainly described and to the extent that description of other elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

Referring to FIGS. 8 to 11 , the SSD apparatus 10 b may include the first inner fan 141 in the case 100. The first inner fan 141 may be attached onto the upper surface of the substrate 210 and accommodated within a first mounting groove 113 of the inner plate 110. At least a part of the first inner fan 141 may be accommodated in the air tunnel 130. The first inner fan 141 may be an air-blowing fan configured to force air in the air tunnel 130 to flow.

According to example embodiments of the inventive concept, the first inner fan 141 may be attached onto the substrate 210 such that the first inner fan 141 blows are in the first direction (e.g., the Y direction). When the first inner fan 141 operates, a flow speed of air flowing in the air tunnel 130 in the first direction increases, and thus, heat transfer efficiency between air flowing along the air tunnel 130 and the case 100 may be increased.

According to example embodiments of the inventive concept, the first inner fan 141 may be disposed in some of the plurality of air tunnels 130. For example, the first inner fan 141 may be disposed exclusively within air tunnels 130 overlapping, in a vertical direction, the controller chip 221, which may generate a relatively large amount of heat. In this case, a flow speed of air flowing in the air tunnels 130 in which the first inner fan 141 is disposed increases, and thus, heat dissipation around the controller chip 221, which generates a relatively large amount of heat, may be reinforced.

FIG. 12 is a perspective view illustrating an uppercase 101 c and a cap member 145 of an SSD apparatus 10 c, according to example embodiments of the inventive concept, and FIG. 13 is a perspective view illustrating the SSD apparatus 10 c, from which the upper case 101 c and the cap member 145 are omitted, according to example embodiments of the inventive concept. FIGS. 14 and 15 are cross-sectional views illustrating the SSD apparatus 10 c according to example embodiments of the inventive concept.

The SSD apparatus 10 c shown in FIGS. 12 to 15 may be substantially the same as or similar to the SSD apparatus 10 described with reference to FIGS. 1 to 4 except that the SSD apparatus 10 c further includes a second inner fan 143 and the cap member 145. For convenience of description, a difference from the SSD apparatus 10 described with reference to FIGS. 1 to 4 will be mainly described and to the extent that description of other elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

Referring to FIGS. 12 to 15 , the SSD apparatus 10 c may include the second inner fan 143 in the case 100. The second inner fan 143 may be attached onto the upper surface of the substrate 210 and accommodated in a second mounting groove 115 of the inner plate 110. At least a part of the second inner fan 143 may be accommodated in the air tunnel 130. The second inner fan 143 may be an air-blowing fan configured to force air in the air tunnel 130 to flow.

According to example embodiments of the inventive concept, the second inner fan 143 may force air to flow in a direction orthogonal to an extension direction of the air tunnel 130. That is, the second inner fan 143 may be attached onto the substrate 210 such that an air-blowing direction of the second inner fan 143 is substantially parallel to a direction (e.g., Z direction) orienting from the lower wall LW of the case 100 to the upper wall UW. When the second inner fan 143 operates, a flow speed of air flowing in the air tunnel 130 increases, and thus, heat transfer efficiency between air flowing along the air tunnel 130 and the case 100 may be increased. In addition, when the second inner fan 143 is attached onto the substrate 210 such that an air-blowing direction of the second inner fan 143 is oriented in the vertical direction, a larger air-blowing fan may be disposed on the substrate 210, and thus, the heat-dissipating efficiency of the second inner fan 143 may increase.

According to example embodiments of the inventive concept, the second inner fan 143 may be disposed in some of the plurality of air tunnels 130. For example, the second inner fan 143 may be disposed exclusively within air tunnels 130 overlapping, in the vertical direction, the controller chip 221, which generates a relatively large amount of heat. In this case, a flow speed of air flowing in the air tunnels 130 in which the second inner fan 143 is disposed increases, and thus, heat dissipation around the controller chip 221, which generates a relatively large amount of heat, may be reinforced. In this case, the second end parts 130E2 of the air tunnels 130 in which the second inner fan 143 is disposed may be blocked by the cap member 145. Because the second end parts 130E2 of the air tunnels 130 are blocked by the cap member 145, most of the air blown by the second inner fan 143 flows toward the first end parts 130E1 of the air tunnels 130.

FIG. 16 is a perspective view illustrating an SSD apparatus 10 d according to example embodiments of the inventive concept.

The SSD apparatus 10 d shown in FIG. 16 may be substantially the same as or similar to the SSD apparatus 10 described with reference to FIGS. 1 to 4 except for an extending direction of the air tunnel 130. For convenience of description, a difference from the SSD apparatus 10 described with reference to FIGS. 1 to 4 will be mainly described and to the extent that description of other elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

Referring to FIG. 16 , the air tunnel 130 formed in the case 100 may extend primarily in the second direction (e.g., the X direction) from the third side wall SW3 of the case 100 to the fourth side wall SW4 of the case 100. A plurality of separation walls 120 extending in the second direction may be provided between the inner plate 110 and the upper wall UW of the case 100. By the plurality of separation walls 120, a plurality of air tunnels 130 separated from each other may be formed between the inner plate 110 and the upper wall UW of the case 100.

For example, when an external cooling fan operates to force air around the SSD apparatus 10 d to flow, the air flows in the second direction along the air tunnels 130 and heat of the SSD apparatus 10 d may be discharged through heat exchange between the air and the case 100. In this case, one end part of the air tunnel 130 exposed through the third side wall SW3 may be an inlet through which external air flows in, and the other end part of the air tunnel 130 exposed through the fourth side wall SW4 may be an outlet through which the external air flows out.

FIGS. 17A and 17B are each a top view illustrating the air tunnel 130 formed in the case 100, according to example embodiments of the inventive concept.

Referring to FIG. 17A, at least one of the plurality of air tunnels 130 may have a width that is different from those of the other air tunnels 130. For example, a width of one air tunnel 130 in the middle of the plurality of air tunnels 130 may be greater than widths of the other air tunnels 130.

Referring to FIG. 17B, an air tunnel 130 may be configured to have a width varying in the extending direction thereof. For example, at least one of the plurality of air tunnels 130 may have a shape in which a width of the at least one air tunnel 130 gradually narrows from the second side wall SW2 to the first side wall SW1. A section at which the width of the air tunnel 130 narrows may overlap, in the vertical direction, the controller chip 221, which generates a relatively large amount of heat. In this case, because a flow speed of air may increase in the section at which the width of the air tunnel 130 narrows, heat dissipation around the controller chip 221, which generates a relatively large amount of heat, may be reinforced.

FIGS. 18 and 19 are cross-sectional views illustrating an SSD apparatus 10 e according to example embodiments of the inventive concept. FIG. 20 is a top view illustrating a part of the SSD apparatus 10 e shown in FIGS. 18 and 19 .

The SSD apparatus 10 e shown in FIGS. 18 and 19 may be substantially the same as or similar to the SSD apparatus 10 described with reference to FIGS. 1 to 4 except that the SSD apparatus 10 e further includes a heat-dissipating fin 150. For convenience of description, a difference from the SSD apparatus 10 described with reference to FIGS. 1 to 4 will be mainly described and to the extent that description of other elements has been omitted, it may be assumed that these elements are at least similar to corresponding elements that have been described in detail elsewhere in the present disclosure.

Referring to FIGS. 18 to 20 , the case 100 may include a plurality of heat-dissipating fins 150 on the upper wall UW of the case 100.

The air passage 151 of the heat-dissipating fin 150 may function as a chimney through which hot air inside the case 100 is discharged to the outside.

According to example embodiments of the inventive concept, the air passage 151 of the heat-dissipating fin 150 may communicate with the air tunnel 130 inside the case 100 through a through hole 108 formed in the upper wall UW of the case 100. In this case, a part of air which has flowed in through the second end part 130E2 of the air tunnel 130 may be discharged to the outside along the air passage 151 of the heat-dissipating fin 150, and heat of the case 100 may be discharged while air flows through the air passage 151.

According to example embodiments of the inventive concept, the heat-dissipating fin 150 may extend primarily in the first direction (e.g., the Y direction) on the upper wall UW of the case 100.

One heat-dissipating fin 150 may have a plurality of air passages 151 that are spaced apart from each other in the first direction.

The plurality of air passages 151 may be spaced apart from each other at constant intervals. A groove 153 extending in the first direction may be formed between neighboring heat-dissipating fins 150. By the groove 153, a constant air flow may be formed at the outside of the case 100. Heat of the heat-dissipating fins 150 may be discharged to the outside while external air flows through the groove 153.

Referring to FIG. 21 , the air passage 151 of the heat-dissipating fin 150 may extend primarily in an inclined direction with respect to a third direction (e.g., the Z direction) orthogonal to the upper wall UW of the case 100. For example, an angle between the extending direction of the air passage 151 and the third direction may be approximately 5° to approximately 30°. When the air passage 151 of the heat-dissipating fin 150 extends in an incline, inflow of external foreign substances to the inside of the case 100 through the air passage 151 may be suppressed.

An angle between the extending direction of the heat-dissipating fin 150 a and the third direction may be approximately 5° to approximately 30°. When the heat-dissipating fin 150 a and the air passage 151 are inclined, inflow of external foreign substances to the inside of the case 100 through the air passage 151 may be suppressed.

As shown in FIG. 24 , an upper surface of the heat-dissipating fin 150 a may have a flat shape and be parallel to the upper wall UW. According to other example embodiments of the inventive concept, unlike that shown in FIG. 24 , the heat-dissipating fin 150 a may have an upper surface of a non-flat shape. For example, the upper surface of the heat-dissipating fin 150 a might not be parallel to the upper wall UW. The upper surface of the heat-dissipating fin 150 a may be inclined. When the upper surface of the heat-dissipating fin 150 a is inclined, inflow of external foreign substances to the inside of the case 100 through the air passage 151 may be suppressed.

In addition, FIG. 25 is a cross-sectional view illustrating an SSD apparatus 10 i according to example embodiments of the inventive concept.

The heat-dissipating filler 160 may include a material having a high thermal conductivity (e.g. a thermal conductivity of at least 10 W/m K).

According to example embodiments of the inventive concept, the heat-dissipating apparatus 300 may include a base 310 and a plurality of heat-dissipating fins 320. The base 310 may be attached to the semiconductor chip 220 and have a plate-like shape. The plurality of heat-dissipating fins 320 may be disposed on the base 310. For example, the heat-dissipating fin 320 may have a line shape extending in the first direction (e.g., the Y direction) from a first edge of the base 310 toward a second edge opposite to the first edge in a top view.

The plurality of heat-dissipating fins 320 may be spaced apart from each other at constant intervals and may be disposed in parallel to each other on the base 310. A groove through which air flows may be formed between two neighboring heat-dissipating fins 320.

Each of the base 310 and the heat-dissipating fin 320 may include a material having an excellent thermal conductivity. For example, each of the base 310 and the heat-dissipating fin 320 may include a material having a thermal conductivity of 10 W/mK or higher. For example, each of the base 310 and the heat-dissipating fin 320 may include Cu, Ni, gold (Au), W, and/or Al. In addition, according to example embodiments of the inventive concept, each of the base 310 and the heat-dissipating fin 320 may include a carbon-based synthetic material, e.g., graphite, graphene, a carbon fiber, a carbon nanotube composite, or the like.

In more detail, the first air passage 331 of the base 310 may penetrate into the base 310 by extending from a lower surface of the base 310 to an upper surface of the base 310. By the first air passage 331 of the base 310, the surface of the semiconductor chip 220 may be exposed. The first air passage 331 of the base 310 may function as a passage through which heat generated by the semiconductor chip 220 is discharged to the outside.

The second air passage 333 formed in the heat-dissipating fin 320 may communicate with the first air passage 331 and be exposed to the outside. The second air passage 333 of the heat-dissipating fin 320 may function, together with the first air passage 331 of the base 310, as a passage through which heat generated by the semiconductor chip 220 is discharged to the outside. The second air passage 333 of the heat-dissipating fin 320 and the first air passage 331 of the base 310 may cooperatively function as a chimney through which hot air heated by the semiconductor chip 220 is discharged upwardly.

A thermal interface material 245 may be disposed between the base 310 of the heat-dissipating apparatus 300 and the semiconductor chip 220. The thermal interface material 245 may reinforce thermal coupling between the base 310 of the heat-dissipating apparatus 300 and the semiconductor chip 220.

When the air passage 330 of the heat-dissipating fin 320 extends to be inclined, inflow of external foreign substances to the air passage 330 may be suppressed.

The air passage 330 of the heat-dissipating fin 320 a may also extend primarily in the inclined direction with respect to the direction orthogonal to the upper surface of the base 310 along the extending direction of the heat-dissipating fin 320 a. When the heat-dissipating fin 320 a and the air passage 330 are inclined, inflow of external foreign substances to the air passage 330 may be suppressed.

As shown in FIG. 34 , an upper surface of the heat-dissipating fin 320 a may have a flat shape and be parallel to the upper surface of the base 310. According to other example embodiments of the inventive concept, unlike that shown in FIG. 34 , the heat-dissipating fin 320 a may have an upper surface of a non-flat shape.

When the upper surface of the heat-dissipating fin 320 a is inclined, inflow of external foreign substances to the air passage 330 may be suppressed.

Referring to FIG. 35 , the heat-dissipating fin 320 a of the heat-dissipating apparatus 300 e may have a bending portion at an upper part thereof.

FIG. 40 is a block diagram illustrating a data storage apparatus 1000 according to example embodiments of the inventive concept.

Referring to FIG. 40 together with FIGS. 1 to 4 , the data storage apparatus 1000 may include, for example, a direct attached storage (DAS), network attached storage (NAS), or a storage area network (SAN). The data storage apparatus 1000 may include a rack 1200 equipped with the SSD apparatus 10 such as an SSD and a cooling fan 1300 disposed to be adjacent to the rack 1200. The rack 1200 and the cooling fan 1300 may be disposed on a support substrate 1100 such as a PCB. In addition, the SSD apparatus 10 may further include a power supply unit 1400 configured to supply power required to operate the data storage apparatus 1000 and a processing unit such as a CPU configured to control an operation of the data storage apparatus 1000.

The rack 1200 may include a plurality of sockets 1210 spaced apart from each other in the second direction (e.g., the X direction), and may equipped with a plurality of SSD apparatuses 10 spaced apart from each other in the second direction. The SSD apparatus 10 may be slid in, for example, the first direction (e.g., the Y direction) and coupled to the socket 1210 in the rack 1200. When the external connector 230 of the SSD apparatus 10 is coupled to the socket 1210, the SSD apparatus 10 may be physically and electrically connected to the socket 1210.

The cooling fan 1300 may provide a forced convection environment to the inside of the data storage apparatus 1000. For example, the cooling fan 1300 may form an air flow in the first direction (e.g., the Y direction) in the data storage apparatus 1000. According to example embodiments of the inventive concept, the SSD apparatus 10 may be accommodated in the rack 1200 such that the direction of the air flow formed by the cooling fan 1300 is parallel to an extending direction of the air tunnel 130 of the case 100. Air introduced by the cooling fan 1300 may effectively cool down the SSD apparatus 10 while flowing along the air tunnel 130 of the case 100, and thus, a heat-dissipating characteristic of the SSD apparatus 10 may be increased. Accordingly, the reliability of the SSD apparatus 10 and the data storage apparatus 1000 including the same may be increased.
